The Antiviral Effects of Rose Bengal and Fluorescein
Archives of Ophthalmology, 1987We evaluated the antiviral effects of rose bengal and fluorescein sodium. The direct antiviral activity was determined by an in vitro direct neutralization assay. The 50% inhibitory dose was 16 micrograms/mL for rose bengal and 460 micrograms/mL for fluorescein.

Photosensitized Oxidation of Oxopurines by Rose Bengal
Photochemistry and Photobiology, 1998AbstractPhotosensitized oxidations of oxopurines (OP) as caffeine, theophylline, theobromine and 1,3,7‐trimethyluric acid (TMU) by Rose Bengal were investigated. In all cases photooxidations occur by a type II mechanism. Reactive and nonreactive 1O2 quenching rate constants by OP were determined in different solvents.

Journal of Radioanalytical and Nuclear Chemistry Letters, 1985
The paper describes an extraction radiometric method for the determination of Rose Bengal content in the radiopharmaceutical preparations of Rose Bengal labelled with131I. Two methods have been studied. The first one is based on the addition of an excess and substoichiometric amounts of Septonex /carbetoxypentadecyltrimethylammonium bromide/ to the ...

131I-Rose Bengal therapy in hepatoblastoma patients
European Journal of Cancer and Clinical Oncology, 1991If conventional treatment modalities have failed in hepatoblastoma patients and no distant metastases can be demonstrated therapy with radionuclide agents can be considered. In 6 patients diagnostic technetium-99m (99mTc)-disofenin and two iodine-131 (131I)-rose bengal scans were made. 2 patients demonstrated specific uptake of disofenin.

The mail had brought from Nice a cardboard box of flowers. The study was hot and close despite the open windows, so when I opened it the scent of the roses filled the air with a new fragrance. I took out the spray on the top, a magnificent cluster of great pink Bengal roses; but the day of glory of this kind is a short one, and the journey was long ...

A spectroscopic study of rose bengal
Chemical Physics Letters, 1989The Raman (50–1750 cm−1), infrared, surface-enhanced Raman and surface-enhanced resonance Raman scattering spectra of rose bengal were studied. It was concluded, based on the analysis of the spectra, that rose bengal has a stable quinoidal structure. A comparison of our results with the literature is presented.

Rotational diffusion of rose bengal
The Journal of Chemical Physics, 1995Picosecond time resolved fluorescence depolarization spectroscopy has been used to measure the rotational reorientation times of rose bengal as a function of viscosity. The variation of viscosity has been effected in two different ways—using different solvents and different compositions of aqueous binary mixtures.

Rose bengal radicals and their reactivity
Journal of the Chemical Society, Faraday Transactions, 1990The one-electron oxidised (radical cation) and one-electron reduced (radical anion) forms of the photosensitiser rose bengal have absorption maxima at 470 nm (molar absorption coefficient 21 100 dm3 mol–1 cm–1) and 420 nm (molar absorption coefficient 37 600 dm3 mol–1 cm–1), respectively.

Distribution and Fate of Rose Bengal
Nature, 1961IT has been suggested1 that complexity of the rose bengal plasma decay curve might be due to the uptake, by organs other than the liver, of different components of the dye. Biorck et al. 2 and Meurman3, using commercial rose bengal labelled with iodine-131, obtained results which made this assumption improbable and have interpreted the plasma decay ...

Rapid labeling of rose bengal and iothalamate with radioiodine
Journal of Radioanalytical Chemistry, 1981Rapid and simple methods for tagging rose bengal and iothalamate with radioactive iodine are proposed. In both cases, the reaction takes place in a penicillintype vial. In the first method, Chloramine-T, was added to a vial containing rose bengal and radioiodide.
